Final answer:
The elevation difference between California's and Louisiana's lowest points is 282 feet, not 290 feet, as California's lowest point is in Death Valley at 282 feet below sea level and Louisiana's lowest point is at sea level.
Step-by-step explanation:
The student is trying to understand the elevation difference between California's and Louisiana's lowest points. Using a shaded relief map, we can see that California's lowest point is in Death Valley, which is at 282 feet below sea level. Louisiana's lowest point is New Orleans, which is at sea level. This means the difference in elevation is 282 feet. Therefore, the correct answer would be C) I disagree; the elevation difference is less than 290 feet.
